Every year, winds over the Sahara Desert sweep up huge plumes of mineral dust, transporting hundreds of teragrams across North Africa and over the Atlantic Ocean. Such dust can be blown for thousands of kilometers and settle in areas as far away as Florida and the Bahamas. The Sahara has been known as the leading source of windblown dust to the Earth's atmosphere. However, Professor David McGee and his team from Yale University have reported that the African plume was far less dusty 5,000 years ago, containing merely half the amount of dust that is transported today. To reach accurate findings, the researchers have reconstructed the African dust plume over the last 23,000 years and observed a dramatic reduction in dust. McGee state that this weakened plume may have allowed more sunlight to reach the ocean, increasing its temperature by 0.15 degrees Celsius which is a slight but significant spike that likely triggered precipitation over North Africa, where climate at the time used to be interestingly far more temperate and hospitable than it is today. This link between reduction in dust and expansion of intense rain into the Sahara could present crucial understanding of not only past but also future climates.

• It is clearly stated in the passage that ----.

Scientists from the University of Michigan in the USA have found that the brain of astronauts changes shape during spaceflight. It is the first study to look into how the brain changes on the journey into space. Researchers looked at MRIs of 26 astronauts who spent time in space. Twelve of the astronauts spent two weeks as Space Shuttle crew members, and 14 spent six months on the International Space Station. ----. Therefore, the researchers concluded that the longer an astronaut spent in space, the bigger the differences in size were

(I) We are running out of space in which to discard our garbage, and our current methods of disposing of it are endangering the environment. (II) Recycling, one solution to this problem, is the process of collecting used materials and manufacturing them into new products instead of throwing them away. (III) Recycling is being done worldwide, for example, in Germany it is a usual practice. (IV) In this way the trash in overcrowded landfills can be reduced. (V) Also materials that are used to make new products can be reduced and natural resources can be saved as well
